Mid-wave infrared photothermal microscopy for molecular and metabolic imaging in deep tissues and spheroids
Mingsheng Li, Yuhao Yuan, Guangrui Ding +11
High-resolution chemical imaging within deep tissues and intact spheroids remains a grand challenge. Here, we introduce mid-wave infrared photothermal (MWIP) microscopy operating i…
Micromolar chemical imaging by high-energy low-photodamage Coherent Anti-stokes Raman Scattering (HELP-CARS)
Guangrui Ding, Dingcheng Sun, Yifan Zhu +5
Coherent anti-Stokes Raman scattering (CARS) microscopy offers label-free chemical imaging capabilities, but its performance is constrained by small Raman scattering cross-section,…
Spatial-offset pump-probe imaging of nonradiative dynamics at optical resolution
Guo Chen, Yuhao Yuan, Hongli Ni +9
Nonradiative photothermal (PT) and photoacoustic (PA) processes have found widespread applications in imaging, stimulation, and therapy. Mapping the generation and propagation of P…
Millimeter-deep micron-resolution vibrational imaging by shortwave infrared photothermal microscopy
Hongli Ni, Yuhao Yuan, Mingsheng Li +5
Deep-tissue chemical imaging plays a vital role in biological and medical applications. Here, we present a shortwave infrared photothermal (SWIP) microscope for millimeter-deep vib…
